One of the Julia creators did a fractal demo [1] recently, including the Sierpinski triangle. Julia is now quite nice for interactive work via the IJulia notebook (IPython kernel for Julia). As a bonus, it does not require a C compiler to g

It doesn't just sprint; the thing gallops . Like a horse. Also, as it warms up, it does a weird jitter-hop and walk-in-reverse thing that is just begging for a remix to an electronic beat. (Sometimes I miss Slashdot. This one deserves

As Q4273j3b pointed out, improving quantitative skills is a must. The upcoming Coursera Machine Learning course would probably be a good start (a lot of the necessary math is introduced in the course). Regarding the degree, credentials are

The MDPnP group has done a lot of work on interoperability and securing interactions. I don't know how much device-specific information they make available, but some of the testing procedures could be helpful for validation: http:&#x2

It is remarkable to me that these kind of considerations can even come up in a language with the high-level expressiveness of Julia. As I work with Julia (and read code in the base and packages), I am continually impressed by the capabili

Yes. There is a patch which provides static compilation support for the system image and should eliminate the startup time. However, the changes from 0.1 have been enormous already, so this will not be merged until 0.2 is tagged.

As mentioned by the others posts, Julia-IPython ("IJulia") support is available. While this is very new, the fundamentals are solid enough that several people are planning to use it for courses this fall. With regard to Pandas, th

I think Julia is the largest application of itself at the moment - the majority of functionality is written in the language itself. The time-to-repl is 2-4s depending on your os and setup. Taking package loading time in to account, it can b

Will it continue development? I'd hate to write a whole suite of software in a new language that no one else will use because the language goes obsolete. My sense is that this is a labor of love as well as necessity, and the folks be

Citing violent crime statistics as proof of a "cultural problem" without any regressors is not particularly helpful. What are the relevant demography-adjusted statistics? There are certainly some (edit: sub-)cultural aspects, but

Thanks for the perspective. Sounds pretty familiar. Aside from missing math syntax, Python by itself/packaged can be great -- until it's slow, which leads to the real problem for me, that compiling mixed Python/C[++] and dep

You really should blog about this! 'Build one to throw away' is a common (very insufficiently applied, in my case) programming aphorism, but it would be neat to hear a take on it from an artist's perspective where you quite l

LLVM does have JIT capability, used by projects including Numba, Julia, Pure and a GLSL compiler (Gallium). Very useful in some contexts but definitely not a silver bullet. Regarding LuaJIT, it compiles in about 10 seconds on a modern compu

It's an interesting idea but the current LLVM JIT is pretty slow so it hurts my head to think about JIT'ing average size C++ programs. Leaving that aside, the cost of doing this for every codepath would probably outweigh the benef

Julia is a pretty cool platform for playing with this kind of thing in a REPL environment - you can dump LLVM IR and corresponding disassembly for any function, with source line annotation (some things are rearranged by the LLVM optimizer,
